But given that we check our smart phones all the time, we needed a bit of digital clarification from the author of kid’s book Dot, about a digitally-obsessed child.

What is the hardest thing for you to unplug?

“I am kind of addicted to my phone, I have to say,” Zuckerberg told us. “But this is the piece of advice I give to everyone and it’s also the hardest: No tech in the bedroom.”

Really? None? What about TV?

“I don’t count it as tech,” Zuckerberg said. “It should count as tech.”

Wait, whaaat? That doesn’t count?

“I talk to so many people and the first thing they do and the last thing they do in the day is not say ‘I love you’ to the person they are sharing a bed with … they’re checking their phone. Wouldn’t it be pathetic if the human race went extinct because we were all playing Candy Crush?”

Randi Zuckerberg before speaking at an event organized by Birthright Israel Foundation at Firehouse 8 in San Francisco, Calif.

Wait a minute, go back to the TV thing.

“At least if you’re watching TV, you’re doing it together,” Zuckerberg said. “But I see couples, they’re just on the sofa together — but they’re both on their laptops. Or they’re in bed — and they’re both on their phones.”

Do you count reading books on electronic devices as using electronics? My wife always complains that I’m reading on an iPad.

“That’s a little blurry,” Zuckerberg said, apparently not wanting to become my couples therapist. “Each couple needs to discuss it and do what they’re comfortable with.”

Her electronics-in-the-bedroom tips:

Plug your phone in at in night — in a different room. Use a natural alarm instead of using your phone all the time as an alarm clock. “You don’t have to, every night, sleep with your phone an inch from your head,” she said.

So how do you reconcile your Facebook connection with unplugging. Has that been hard?

“It’s not been hard. I look at great entrepreneurs like my brother, like the Twitter founders, like Steve Jobs, and lot of those people very publicly talk about meditation and the role meditation plays in their lives.. You don’t come up with brilliant ideas by always answering e-mails and responding to every text messages. You do it by giving yourself head space every day to completely be creative.”
